Given the universal set U = {v, w, x, y, z), and subsets A = {v, w, z} and B = {x, y, z), indicate the roster
lukranit [14]
If U = {v, w, x, y, z} and A = {v, w, z}, then
A' = {x, y}
(A' is the complement of A - it's the set containing all elements of U that are not in A)
If B = {x, y, z}, then
B' = {v, w}
Their their union is
A' U B' = {v, w, x, y}
Answer: 2
Step-by-step explanation:
The answer is 1.5 months
explanation:
5/2 = 2.5
15/4 = 3.75
2.5 per month
3.75 per x months
x = (3.75×1)/2.5
x = 3.75/2.5
x = 3/2 = 1.5 months
